Dual Wall Heat Shrink Tubing, SBRS-(3X)GLW

Model: SBRS-(3X)GLW

Flexible, thick wall, adhesive-lined heat shrinkable tubing

SBRS-(3X)GLW flexible, thick wall, adhesive-lined heat shrinkable tubing is made from polyolefin through co-extrusion process, and using hot-melt adhesive. This dual wall heat shrink tubing is designed for both insulation and sealing of complex parts, and protection of wire bundles and metal tubes against water and moisture.


Features
  • Flexible
  • Low longitudinal shrinkage
  • Thick adhesive liner bonding to a wide variety of plastics, rubber and metals, forming an effective barrier against fluids and moisture
  • Continuous operating temperature: -45℃~125℃
  • Min shrink temperature: 110℃
  • Shrink ratio: 3:1
